     17 # NAME

     19 CURLOPT_PUT - make an HTTP PUT request

     29 # DESCRIPTION
     30 
     31 A parameter set to 1 tells the library to use HTTP PUT to transfer data. The
     32 data should be set with CURLOPT_READDATA(3) and
     33 CURLOPT_INFILESIZE(3).
     34 
     35 This option is **deprecated** since version 7.12.1. Use CURLOPT_UPLOAD(3).
